To 117/ //./tf)/'ll. it mr/y concern: i Be it known that I, l'iEIXHICH Dnciia'nrs, a subject of the King of Prussia. residing at condense the vapors Charlottenburg. Germany. have invented niit the oil particles to drop certain new and useful improvements in crank chamber. Condensing- Ventilators for Engines, of f (in top of the conduit 10 a head 13 of which the following is a specification. any-suitable construction having an annular The present invention relates to means for passage or chamber 1 1: that communicates ventilating the crank casings of engines, with the pas--a1gt in the conduit 10 and terparticularly of the internal combustion i minates at a point slightly below the upper t vpe, and has for its object to improve their l end of the breather pipe fl. .is shown, the construc ion and operation. he; d

the center of the breather pipe and air pas-sine; downward therethrough tends to as they rise and perback into the comprises a pair of thin metal plates l or a consideration of what 1 believe to that are down turned at their outer edges be novel and my invention, attention is mi and are separatml from each other by space rooted to the accompanying description and blocks The edge of the under disk extends below the upper end oi the breather pipe so that vapor esca 'iing from the latter must flow past the annular passage between said plates. The relation of the head and breather pipe claims appended thereto.

In the drawing is shown an internal conibustion engine in vertical section.

The engine may be of any suitable construction and operate on any desired cycle. As illustrated it is of the two-cycle type, there being two oppositely moving pistons in each cylinder.

1 indicates the base or crank casing of the engine containing a chamber :2 in which the crank shaft 3 rotates. In the relatively air tight chamber 2 is a body of lubricant for lubricating the cranks, pistons, etc. The connecting rods for the upper-and lower pistons have been omitted in the interest of clearness. At the top of the crank case is a receiver 4: that supports one or more cylinders 5. In the cylinder are scavenging ports 6 receiving air from the chamber in the receiver and ports T for the exhaust products of combustion. At the sides of the cylinder and formed in the receiver are. openings 8 through which the upper piston connecting rods extend.

Mounted at some convenient place on the crank casing is a relatively large tubular is such that the vapors can escape from the latter without undue restriction. Further, owing to the relation of the parts, the said escaping vapors are sucked into theconduit 1O along with the the conduit 19. in a two-cycle engine shown, theeonduit 12 supplies air to the scavenging pump which in turn delivers it to the chamber in the receiver 4 and from there to the working cylinrhr. The pump is not shown as it seems unnecessary to an urnlerstanding of my invention. in the case of a tour-cycle eneii'ie tlie air from the (on duit 12 may pass directly to the cylinders, subject, of course, to thiv usual valve control. in the event that it is urn'lesirahle for any reason to entrain the uncondei'ised gases I from the crank chamber with the fresh air supplied to conduit 12, the shape of the head may be so modified as to prevent the gases and air from mixing. in other Words, the

member 9 commonly referred to as a two features of my invention: (2., condoms breather pipe or ventilator. As the pis- 111g of the Oil vapors, and supplying uncontons move in and out this member or pipe deused gases to the Working cylinder can serves to equalize diilerences of pressure bebe used ti'igether or separately. By unscrew tween the inside and theoutside of the crank ing the tube 10 the breather pipe can be chamber. The pipe also serves as a means, easily removed. The conduit 12 may be formed separately instead ot'forming part of the base casting".

In accordance with the provisions of the l patent statutes, 3: have desrri any suitable Way; as for example, by screwciple of opeaition of my invention, tog-ether ing it into the Wall 11 of the air carrying with tl apparatus which It now consider to conduit 12. The conduit 10 extends through i represent the best embodiment thereof;

In order to condense these relatively hot oil vapors a conduit 10 is provided that is supported in supply'of fresh air and flow with it through i U... u JO L116 P1311" l desire to have it rutus shown is only invention can \Vha 63.115111 by Lelia-s Pei 1.
